We divide 21360121 by 543
We're looking to find how many times 543 goes into 21360121.

Going ahead to step 1:
543 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 543

Step 2:
543 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 543

Advancing to step 3:
The number 543 fits into 213 0 times, leaving a remainder of 213.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 213 to get 213.
Grab the next digit (6) from the dividend, add it to 213, then carry on: 2136 / 543

On to step 4:
543 goes into 2136 3 times with a remainder of 507.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 1629 from 2136 and we're left with 507.
Include the next digit (0) from the dividend after 507, then repeat: 5070 / 543

On to step 5:
543 goes into 5070 9 times with a remainder of 183.
Use 9 as the next digit of our solution. 
Result so far: 39.0
The remainder is 183 after subtracting 4887 from 5070.
Bring next digit (1) of the dividend behind the 183 and repeat the process: 1831 / 543

Step 6:
The number 543 fits into 1831 3 times, leaving a remainder of 202.
Write down 3 as next digit of the result. 
Result so far: 393.0
If we take 1629 away from 1831, we end up with 202.
Append the next digit (2) from the dividend to 202 and continue with: 2022 / 543

Step 7:
543 can be fit into 2022 3 times, resulting in a remainder of 393.
Record the quotient 3 as the next digit in the result. 
Result so far: 3933.0
The remainder is 393 after subtracting 1629 from 2022.
Take the next digit (1) from the dividend and append it to 393, then repeat: 3931 / 543

Let's proceed to step 8:
543 goes into 3931 7 times with a remainder of 130.
The number 7 becomes the next digit in our result. 
Result so far: 39337.0
Subtract 3801 from 3931 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 9:
543 can be fit into 1300 2 times, resulting in a remainder of 214.
Write down 2 as next digit of the result. 
Result so far: 39337.2
If we take 1086 away from 1300, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Going ahead to step 10:
2140 divided by 543 is 3 with a remainder of 511.
Write down 3 as next digit of the result. 
Result so far: 39337.23
If we take 1629 away from 2140, we end up with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Advancing to step 11:
If we divide 5110 by 543, we get 9 and a remainder of 223.
Put 9 as the next digit of the answer. 
Result so far: 39337.239
If we subtract 4887 from 5110, we get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 12:
543 goes into 2230 4 times with a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 39337.2394
Subtract 2172 from 2230 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 13:
If we divide 580 by 543, we get 1 and a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 39337.23941
The remainder is 37 after subtracting 543 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 14:
When dividing 370 by 543, we get 0 with a remainder of 370.
Write down 0 as next digit of the result. 
Result so far: 39337.23941
If we subtract 0 from 370, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 15:
543 can be fit into 3700 6 times, resulting in a remainder of 442.
The number 6 becomes the next digit in our result. 
Result so far: 39337.2394106
The remainder is 442 after subtracting 3258 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Step 16:
543 can be fit into 4420 8 times, resulting in a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 39337.23941068
Deduct 4344 from 4420 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 39337.23941068 and a remainder of 7.6e-08.
